Why it matters

Predicting and testing is the heart of the scientific method in miniature. When a child guesses what will happen, carries out the test, and notices whether the guess was right, they learn to use evidence to confirm or revise their ideas.

What mastery looks like

Makes a prediction before acting, such as guessing whether an object will sink or float.
Compares the outcome to the prediction and says whether the guess was right or wrong.

How to observe it

Before an experiment, does the child state what they think will happen?
After testing, does the child compare the result to the original prediction?

Accessibility

Let children record predictions by pointing to picture cards or sorting objects rather than only speaking.

Safety

Supervise closely around water and keep small test objects out of reach of mouthing.
